ATTACHABLE sTlToHl- Ess BUCKLE.

Specification of Letters Patent.

Patented Feb. 12, 1907.

To all -.w7w71t it m/a/ z/ concern:

Be it known that I, MrEcZYsLAw BARA- BASZ, a-citizen oi' the UnitedStates, residing at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Attachable Stitchless Buckles, ofwhich the followingA is a specification.

This invention relates to improvements in detachable one-piece metalbuckles.

One obj ect of the invention is toconstruct an improved buckle havingthree cross-bars which may be formed of a single piece stamped from asheet of metal and which may be readily attached to the straps or beltwhich it is to secure together without the neremoval from the strapswhile such straps Another object of the invention is to irnprove theconstruction of` a three-bar buckle so as to simplify the threading ofthe webs or straps and to enable the ready adjustment by the movement ofthe straps through the buckle and at the same time avoid theliaadjusted.

`Another object of the invention is to proreason'of its simplicity inattachment to the justment without pressure against the body, and alsoby reason of the fact that it is constructed of a single piece of metal,and there- I am aware that it has heretofore been procross-bars-such,Yfor example, as is illustrated in the patent to Tuch, No. 470,625, andalso in the Woodman patent, N o. 89,110 but the construction of thosebuckles is such that they cannot be stamped out Oomplete from a sheet ofmetal and are incapble of engaging the web to prevent Accidentalslipping. By my arrangement of bars and engaging devices theobjectionable features of all three-bar buckles now known to me areovercome.

The invention is illustrated in the accompanying drawings, in which*Figure 1 illustrates a perspective view of i the buckle as used forsurgical purposes. f Fig. 2 shows the same buckle in plan. Fig. l 3shows a perspective view of my improved buckle for ordinary use; Fig. 4,an end view i of the same. Fig. 5 shows a sectional view i through thebuckle and straps. Fig. 6 illustrates a front face view of the buckleattached to the webs or straps, and Fig. 7 shows a rear view of thebuckle and the straps attached.

Referring to the drawings by numerals, 1 designatesthe two parallel sidebars; 2, one end bar g 3, the other end bar, and 4 the centralcross-bar. All of these bars are stamped -from a plate of sheet-steel insuch manner as to form a lange 5, which projects inwardly from the outeredge of at least three of said bars, whereby to stilien the buckle-plateand enable a thin sheet of steel to be employed with good results.

By reference to Figs. 1, 3, and 5 it Will be noted that the centralcross-bar 4 has an in clined position with respect to the two endbars-that is, one longitudinal edge 6 of the bar 4 has position in aplane beneath or below the outer surface of the bars l, 2, and 3- whilethe other edge 7 of said bar has position in a plane substantially inline with said outer surface and is provided with a plurality ofsharp-pointed teeth 8, which project outwardly in an inclined direction.The inclination, however, of this Central cross-bar and the pointedteeth thereon may be varied and may be more or less than'that shown.Adva'ntageous results are gained by thus inclining this centralcross-bar. For example, it enables the web or strapy to be readily fedthrough the slot 9. It insures and compels the teeth 8 to engage theunder strap to hold it in the adjusted position, and it removes onesharp edge 6 oT' the cross-bar from the path of the under strap duringits adjustment and enables said adjustment to be made with a minimumamount of friction, and consequently without wear or strain on thestraps. By reference to Fig. 5 it will also be noted that the Bange 5 onthe end bar 2 performs a useful function in addition to its utility as astiffening means, in that it serves as a friction edge which pressesagainst the free end of the ou ter strap l() and prevents this strapfrom working or moving backward toward the central bar land by suchbackward movement carrying with it the inner strap 11, which lattermight thus work over the teeth 8 and become loose.

In the present instance I prefer to arrange the teeth 8 on the centralbar in pairs and to locate said pairs of teeth at opposite ends of thebar. rlhe object and advantage of this construction and arrangement ofthe teethis lOO IIO

that in the formation of the straps l() and 11 when the latter areattached to the rear or back of mens garments the opposite edges 12 ofthe straps are thicker than the portions between the said edges byreason of the fact that the.. cloth or material from which the stra sare made is turned under and then stitc ed, as at 13, to prevent thesaid edges from raveling out. rI`his construction therefore forms adouble thickness of material along said longitudinal edges, and if thecentral cross-bar had but a single tooth at each end said single toothmight fail to properly engage the material and permit the strap to slipfrom its adjusted position. By providing two teeth at each end of thebar said teeth engage the strap on opposite sides of the stitch-line 18and the engagement with the strap is insured and the objection explainedovercome. The end bar 3 is also provided with sharp-pointed teeth 14,which project therefrom and turn inwardly toward the inner side of thebuckle.

It will thus be seen that the peculiar combination of three cross-barswith the outwardly and inwardly pointed teeth all coact in such a manneras to enable the straps to be easily fed through the buckle, permittheir ready adjustment when desired, and insure a positive engagementbetween the outwardly and inwardly projecting pointed teeth and the twostra s to prevent slipping of said straps after the adjustment has beenma de.

It will valso be seen that the buckle is made from a single plate andthe teeth arranged in such manner as to enable the formation of theentire buckle by a die.

The end bars 1 are both provided with the flange 5; but this lian e hasa curved edge 15, which serves to broa en the flange at a central pointadjacent the central cross-bar, and thereby facilitate the grasp ing andmanipulation of the buckle during the act. of threadinvr and adjustingthe straps.

n addition to the features hereinbefore described, which are common tothe buckles shown in all the figures of the drawings, I

rovide a slot 16 in the end bar 3, as shown 1n Figs. 1 and 2, and a tab17 or piece of webbin of any suitable material is passed throu h saislot, so as to enable the buckle to be drawn along the outer strap 10 toshorten the latter when employed for surgical puroses. It is obviousthat by grasping the ee end of the outer strap and holding it undertension the buckle may be readily drawn by the tab or webbing 17 withoutpressure on the buckle-plate.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A buckle comprising a singleplate having two 'side bars; two end barswhich coni nect the side bars and one of said end bars having teeth atits inner edge, and an inclined toothed bar between the end bars, theteeth of the inclined bar confronting the teeth of the end bar. p

2. A buckle comprising a single plate having two side bars, two end barsconnecting the side bars and one of said end bars having a 'plurality ofteeth which 'project from the inner side and beyond the inner surface ofthe buckle-plate and said buckle also having an inclined cross-bar withteeth along its outer edge.

3. A buckle comprising' a single plate having side bars, end barsconnectin the side bars and one of said end bars having a plurality ofteeth along its inner edge and said buckle also having a central barwith a pair of teeth at each end thereof-said pairs of teeth on thecentral bar 'projecting toward the end bar with the teeth.

4. A buckle comprising a single 'plate having side bars, end barsconnecting the side bars and one of the end bars having teeth which arepointed and are bent inwardly beyond the inner surface of thebuckle-'plate and said buckle having a cross-bar between the endbars-said cross-bar also having pointed teeth which project outwardlyand beyond the outer surface of the buckle-plate.

5. A buckle comprisinga single plate having side bars, end barsconnecting the side bars and one of the end bars having a plurality ofinwardly-bent teeth, while the other end bar is toothless--said sidebars and tothless end bar having a flange at their outer edges, and acentral cross-bar having teeth which project outwardly beyond thebuckle-plate and which confront the teeth on the end bar.

6. A buckle comprisin a sin le plate having side bars, a toothless angeend bar connecting one end of the side bars; a flangeless toothed barconnecting the other end ofthe side bars and provided with a slot and across-bar also connecting the side bars between the two end bars andsaid cross-bar having teeth at that side which confronts the teeth ofthe end bar.

7. A buckle comprising a single plate having side bars, end barsconnecting the side bars and one of said end bars having'- teeth; meansattached to the toothed end bar by which the latter may be drawnlaterally, and a cross -bar also connecting the side bars and havingteeth which 'project laterally toward the end bar with the teeth.

In testimony whereof I afliX my signature in presence of two witnesses.
